Find LCM of 493,136,171,448,689 with Prime Factorization
| 2 | 493, 136, 171, 448, 689 |
| 2 | 493, 68, 171, 224, 689 |
| 2 | 493, 34, 171, 112, 689 |
| 17 | 493, 17, 171, 56, 689 |
| 29, 1, 171, 56, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 29 x 1 x 171 x 56 x 689 = 26021975616
Therefore, the lowest common multiple of 493,136,171,448,689 is 26021975616.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
493 x 136 x 171 x 448 x 689 = 3538988683776
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
493 : 1, 17, 29, 493
136 : 1, 2, 4, 8, 17, 34, 68, 136
171 : 1, 3, 9, 19, 57, 171
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,136,171,448,689, is 1.
Now, the common factors can be found like this.
493:17x 29
136:2x 2x 2x 17
171:3x 3x 19
448:2x 2x 2x 2x 2x 2x 7
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 17 = 136
Therefore, the value for common factors is 136.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 3538988683776/(1x136)
LCM = 3538988683776/136
LCM = 26021975616
Thus, we can understand that the LCM of 493,136,171,448,689 is 26021975616.
